Product Description:

The HCS02.1E-W0012-A-03-NNNV-AA is a drive controller built by Bosch Rexroth Indramat within the HCS IndraDrive Controllers series. As an HCS drive controller, it interfaces between the line supply and servo or induction motors, providing regulated power and diagnostic functions for coordinated motion tasks in automated production cells, packaging machines, and material-handling lines. By combining power electronics with closed-loop control, it helps maintain commanded speeds and torques while protecting connected equipment from overcurrent or supply disturbances.

This unit handles a device peak output of 12 A, giving short-term headroom for rapid acceleration sequences without saturating the inverter stage. It accepts a three-phase input range of 3 x AC 200...500 V ±10%, allowing the same hardware to operate on low-voltage or high-voltage plant networks. The supported motor power range spans 1.5 to 11 kW, so one controller type can cover multiple motor sizes on a machine. An IP20 housing limits finger access and requires installation inside a control cabinet with filtered airflow. Thermal management is provided by internal air cooling through an integrated blower that moves cabinet air across the heat sink without external ducts or water lines.

The controller is identified as Design Version 1. It belongs to the HCS02 line and uses the common mechanical format of that subgroup. The integrated power section operates in an Infeeding / Feeded topology, which allows regenerative braking energy to return to the DC bus or be dissipated as required. Control electronics and the brake transistor receive a separate DC 24V supply derived directly from the shared DC link. This arrangement removes the need for an external auxiliary power converter.
